GRAINSEPARATOR.

ideales Specification of Letters Patent.

Application filed June 23, 1314. Serial No. 846,885.

To all trimm t may concern.'

Be it known that I, JOHN GATELY, a citiren of the United States, residing at Gretna, in the county of Sarpy and State of Nebraska, have invented new and useful lmprovements in Grain-Separartors, of which the following` is a specification.

'lhe invention provides a rack intended chiefly for separating grain, said rack embodying sets of toothed hars which are con nected in series and arranged to have a reciprocatory movement imparted thereto, the purpose being to provide a separating surface which will effectively support straw, colis and the like, while at the'same time affording a ready escape for the detached kernels of grain.

rlhe invention consists of toothed bars and fluted strips at the sides of such hars, such strips being arranged in the spaces formedhetween the hars and having crimps which serve to direct the grain downward and to urge the straw and cobs forward to the tailings or delivery end of the separating` surface.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.

ln the drawings hereto attached z-Figure l is a top plan view of a grain separator embodying the invention. Fig. 2 is a longitudinal section. Fig. 3 is a cross section on the line -m of Fig. l, looking in the direction of the arrows. Fig. et is a cross section on the line lv/--g/ of Fig. 1, looking in the direction of the arrows. 5 is a detail perspective view of a portion of one of the toothed hars and fluted and crimped strip cooperating therewith. Fig. 6 is a detail view of a portion of one of the fluted and crimped strips.

Corresponding and like parts are referred to in the following description, and indicated in all. the views of the drawings, by the same reference characters.

The numeral l designates generally a main frame for supporting the working parts.

Side pieces 2 project upward from the main frame and prevent lateral displacement of the grain passing through the machine and over the separating surface.

s. crank shaft 3 is located at one end of the frame and a second shaft t is mounted in the frame near the crank shaft and is provided near opposite ends with hars 5 which project and form opposed arms.

The separating surface is formed of a plurality of toothed hars 6 which are arranged side hy side between the side pieces 2 and spaced apart a comparatively short distance, rlihe hars 6 are of like formation, the upper edges thereof being provided with teeth and their sides being straight. The toothed hars are arranged in two sets, the hars of each of the sets being connected for simultaneous movement and the hars of one set alternating with the bars of the other set, the two sets of hars receiving a simultaneous movement in opposite directions so that while the hars of one set are returning, the hars of the other set are achfancing` Cross pieces 7 connect the front ends of the hars of the several sets and other cross pieces 8 connect the toothed bars near their rear ends, the cross pieces S projecting loevond the side pieces 2 and receiving the lower ends of hangers 9 which support the bars in a manner to admit of their receiving a reciprocating movement. Links l0 connect one set of toothed hars with the upper arms of the hars 5 and other links 1l connect the other set of toothed hars with the lower arms of the bars 5. A. rocking movement of the shaft 4t results in an opposite reciprocating movement of the two sets of toothed bars.

Links l2 connect the crank portions of the crank shaft 3 with the bars 5. Rotary movement is imparted to the crank shaft in any convenient manner and results in a rocking movement of the shaft 4. The two sets of hars in addition to their reciprocating movement also have a vertical movement imparted thereto with the result that the straw, colos or the like is elevated and at the same time advanced, the movement being gradual and step by step, with the result that the grain is loosened and ample opportunity afforded for the escape of the same, such grain passing through the spaces formed between the toothed hars whereas the straw, colis and the like is carried over the end of the surface and discharged in the well known manner.

A metal strip 13 extends along one side of each of the toothed bars and is arranged in the space formed between proximal sides of adjacent toothed bars. The metal strips 13 are iuted thereby forming vertical spaces 14 which insure a positive escape for the grain. rhe outer surfaces of the parts of the strips 13 arranged between the vertical spaces 14C are formed with crimps 15, such crimps being inclined and the crimps upon opposite sides of each of the vertical spaces 111 being oppositely inclined withthe result that they assist materially in the separation and discharge of the grain and in the forward movement of the straw, colis and the like. Each of the toothed bars is provided with a metal strip 13 and such strips are arranged upon thesides of the toothed bars facing in the same direction. The strips 13 are spaced from the sides of the bars between which they are arranged eXcept at the points of attachment thereto and as result a separating surface is provided which insures a maximum delivery of the straw, cobs and like material while at the same time providing ample escape for the grain. The tendency of the strips 13 to spring laterally prevent any possible choking or binding of the grain in the vertical spaces or discharge outlets 14:.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and' while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, l desire to have it understood that the deviceV shown is merely illustrative, and thatY such changes may be made when desired as are within the scope of the invention as claimed.

Having thus describedthe invention, what is claimed as new is 1. A separating surface for grain, the same comprising a plurality ofspaced bars, means for imparting a reciprocating movement thereto, and strips arranged in the spaces formed between the bars and crimped throughout their length to provide a plurality of grain outlets.

2. A separating surface for grain comprising a pluralityl of spaced bars, means for imparting a reciprocating movement thereto and strips arranged between the bars and formed' throughout their length with flutes forming a plurality of grain outlets and having the portions between the utes formed with crimps.

3. A separating surface for grain comprising ay plurality of spaced bars, means for imparting a reciprocating movement thereto and strips arranged between the bars and formed throughout their length with flutes forming a plurality of grain outlets and having the portions between the flutes formed with crimps, the crimps upon opposite sides of the flutes being reversely inclined.

'-1. A separating surface for grain, the same comprising a plurality of spaced bars, and fluted strips arranged in the spaces formed between the bars and spaced from the sides of the bars to admit of a lateral yielding to prevent choking or binding of thev grain in the outlets formed by the flutes.

5. A grain separating surface compris ing two sets of toothed bars arranged to receive an opposite reciprocating movement, the bars of one set alternating with the bars of theother set and fluted strips attached to the sides of the bars facing in the same direction, such fluted strips being arranged between adjacent bars.

6. A grain separating surface comprising two sets ofl toothed bars arranged to receive an opposite reciprocating movement, the bars of one set alternating with the bars of the other set and fluted strips attached to the sides ofthe bars facing in the same direction, such flutedstrips being arranged between adjacent bars and having the portions between the flutesV oppositely crimped, said strips being spaced from the bars tol yield laterally and.v preventl clicking or binding offV the grain in the outlets formed between adjacent toothed bars.

ln testii'nony whereof'v I aliix'my signature in presence of two witnesses.
